usually i use my high mileage cushion trainers for all road stuff incl races, but, I went running in a pair of low cushion shoes usually reserved for the gym ( ie don't look like they belong to a tramp or runner ! ) when my other two pairs were wet and muddy and 'felt' a distinct bit more nippy and purposeful.

I'm only around 40 mins for 10k and at 12.5 stone, 5ft9 with 8% fat not that light on my feet and not likely to get more than a few pounds lighter

previously i'd have always thought racing flats were for fast, lightweight runners...is this a an ignorant misconception on my part ?

cos i'm thinking of getting some for racing now, good idea or not ?

Thanks
